GRUB won't boot Gentoo Linux :(

shane25119 · 02-06-2004, 08:50 PM

Hello
I recently installed Gentoo and I am having some problems with GRUB. I can boot GRUB just fine.... my problem is when i attempt to boot into Gentoo i get this

STEP 4a: Mounting root
mount: Mounting /dev/hda3 on /newroot failed: Invalid arguement
Could not mount specified ROOT, try again
Root block device unspecified or not detected.
Please specify a device to boot, or "shell" for a shell.
:

Now, my /etc/fstab looks like this:

/dev/BOOT /boot ext2 noauto,noatime 1 2
/dev/ROOT / reiserfs noatime 0 1
/dev/SWAP none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro,user 0 0
none /proc proc defaults 0 0

My /boot/grub/grub.conf appears as this:

default 0
timeout 30
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

#all above works fine in /boot/grub/grub.conf

#For Booting GNU/Linux
title=My Example Gentoo Linux (recent genkernel)
root (hd0,0)
kernel (hd0,0)/boot/kernel-2.4.22 root=/dev/ram0 real_root=/dev/hda3 init=/linuxrc
initrd (hd0,0)/boot/initrd-2.4.22-gentoo-r5

any help is greatly appreated

You need to change the BOOT to reflect your boot partition, like /dev/hda1, and you need to change your ROOT to reflect your / partition, like /dev/hda3, and you need to change your SWAP to reflect your swap partition, like /dev/hda2. Those capital letter words are there so you can replace them.

i.e.

Code:

/dev/hda1   /boot ext2 noauto,noatime 1 2
/dev/hda3   / reiserfs noatime 0 1
/dev/hda2   none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro,user 0 0
none /proc proc defaults 0 0

Is Gentoo Linux on your 1st partition of your 1st hard drive?

Also if you use root (hd0,0), you do not need to add it to the kernel or initrd.

sorry guys:

my fstab is properly set... i just copied that from the gentoo install guide

hda1: boot
hda2 swap
hda3 root

i found something in the gentoo forums that may work..... i'll keep you guys posted

thanks for the input

ter_roshak · 02-06-2004, 09:53 PM

I'm pretty sure GRUB is (hd0,0), I just went through another Gentoo stage1 install last weekend.... Also, Shane, you do have to change those parameters in your fstab, unless you define them before those lines, which I did not see. Good luck...

shane25119 · 02-06-2004, 10:55 PM

Josh,
My fstab uses the actual hda1, hda2, instead of BOOT,. SWAP it was just an honest mistake that i posted it that way thanks for wishing me luck i shall keep you guys posted

Shane,

Ok, sorry about that then. Just trying to help...<g>

Josh,
I noticed you are using gentoo as well. Did you have to do any special configuration to make it work? I read on the gentoo forums that the latest kernel 2.4.22-gentoo-r5 has a bug where reiserfs does not load properly, so therefore it is nessary for a special kernel configuration to be ran thru the use of genkernel --menuconfig all, i tried that and it failed, I am trying now under ext3.
just curios

I couldn't get gentoo to boot until i removed the (hd0,0) from the kernel line. Here's what my grub file looks like:

Code:

title=Gentoo Bootsplash
root (hd0,0)
kernel /boot/kernel_020504 root=/dev/hda3 hdd=ide-scsi hdc=ide-scsi video=vesa:ywrap,mtrr $
initrd=/boot/initrd-1280x1024

and my fstab looks like this:

Code:

/dev/hda1               /boot           reiserfs        noauto,noatime,notail           1 1
/dev/hda3               /               reiserfs        noatime                 0 0
/dev/hda2               none            swap            sw                      0 0

Maybe this will help you out.

What is the root=/dev/ram0 for? Have you tried getting rid of that? I would suggest making your grub file as simple as possible until you get it to boot, and then mess with it using a new menu entry so that if you have to boot, you always can.

i'm gonna give that a try thanks

ter_roshak · 02-07-2004, 11:28 PM

Shane,

I did not have to do anything special, my grub.conf is as follows:

Code:

default 0
timeout 10
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
 
title Gentoo 2.4.22
kernel (hd0,0)/boot/bzImage

Note: I'm not using initrd because I did not use the genkernel, I manually configured everything.

My /etc/fstab is as follows:

Code:

/dev/hda1           /boot       reiserfs  noauto,notail   1 1
/dev/hda3           /           reiserfs  noatime         0 0
/dev/hda4           /beta       reiserfs  noatime         0 0
/dev/hda2           none        swap      sw              0 0
/dev/cdroms/cdrom0  /mnt/cdrom  iso9660   noauto,ro       0 0
/dev/cdroms/cdrom1  /mnt/cdrom1 iso9660   noauto,ro       0 0
/dev/fd0            /mnt/floppy auto      noauto          0 0

none      /proc   proc    defaults    0 0
none      /dev/shm  tmpfs   defaults    0 0

I don't know if my splash image works though...(not sure what its supposed to look like).

After you installed GRUB, did you do the root (hd0,0) then setup (hd0,0)?

-Josh

shane25119 · 02-08-2004, 11:59 AM

yeah i did, the splash image is just a graphical look for GRUB

shane25119 · 02-08-2004, 03:20 PM

i have successfully booted into the system

now i am emerging kde and will soon have Gentoo Linux ready to roll

busbarn · 02-08-2004, 07:42 PM

Congratulations!

shane25119 · 02-08-2004, 09:44 PM

thanks busbarn

getting the ethernet card to work took some snooping on the gentoo forums...

for any one in my pinch, in the terminal just type in dhcpcd ethx

where x is your network card

i did some quick math and it seems it will be 41 hours total for KDE (and from the compiling i have watched it is installing everything under the sun that comes w/ kde)

i want to make sure it works when its done..... for anyone else who has installed gentoo (stage3) is there any X configuration needed?
